A bit of an overstatement.
Not really. The Oil Sands is a huge complex of hydrocarbons and Canada is the 3rd largest reserve nation on Earth next to Saudi Arabia and Venezuela! This effort to stop the Keystone is the cover for extreme green radicals who want to block the entire development of the Sands. They want it stopped, which means we would be forced to purchase more and more oil from terrorists. There are trillions of dollars in sellable energy in Canada that will also be carried, refined and sold in the US. One needs to realize the Sands will also be a gigantic boost to America’s superior heavy equipment and oil services industries, which will supply the future development. The artificial shutdown, limits a huge supply of energy that will need to be purchased from terrorist nations, takes our wealth and makes terrorist states stronger.
These hydrocarbons lower the cost of heating homes, of electric power, of chemical production, of fertilizer, of the cost of food, health products and the building blocks of thousands of products. This also makes our industries highly competitive bringing new factories to our shores. Also our wealth does stay in the US, and the sale of these products overseas does reduce our trade deficit, and our debt.
Fracking natural gas itself in America has increased each household’s disposable income by $1200.
It is not an overstatement for North America - it is a huge resource which is why the green extremists are so bent on shutting it down.
